Primary Clue
For me, one of the primary clues of Norjak is the knowledge that DB Cooper possessed, namely, that the 727 could be jumped, the aft stairs could be lowered in flight, and the plane could remain stable and airborne. As has been stated numerous times, where could DB Cooper learn that?
Vietnam and covert ops? Boeing's 727 test facilities? Cool bars in Moses Lake or Saigon?
I've combed through CIA and Air America stuff, with no success. Learning about ops in Laos was cool, though. But no 727s. And 20 emails to retired Air America staff have gone with response. Ahhh, good ol' AA...
So, now I'm turning towards Boeing and its Moses Lake facility. Got a lead on an ATC from there. Currently sorting who what and where. Larsen AFB, Grant County Airport, Boeing.
Any thoughts, contributions?
